John Culshaw‘s book Ring Resounding begins with: “In Vienna, on the afternoon of September 24, 1958, Decca began the first commercial recording of Richard Wagner’s Der Ring des Nibelungen; seven years later, on the evening of November 19, 1965, every note and every word of Wagner’s huge masterpiece had been recorded. Nothing comparable in scope, cost, or artistic and technical challenge had been attempted in the history of the gramophone.”
